Fulvitalea axinellae gen. nov., sp. nov., a member of the family Flammeovirgaceae isolated from the Mediterranean sponge Axinella verrucosa.

ABSTRACT

The yellow-pigmented, non-motile, Gram-negative, strictly aerobic, rod-shaped bacterial strain VI.18(T) was isolated from the Mediterranean sponge Axinella verrucosa collected off the coast near Sdot Yam, Israel. Results from 16S rRNA gene sequence analysis indicated that the isolate belonged to the family Flammeovirgaceae. The highest nucleotide similarity (91.4 %) occurred with Aureibacter tunicatorum A5Q-118(T). The predominant cellular fatty acids of strain VI.18(T) were iso-C15  0 (56.0 %), iso-C17  1ω9c (22.8 %) and C16  0 (7.4 %) and its major respiratory quinone was MK-7. The DNA G+C content was 47.5 mol%. The strain could readily be distinguished from its phylogenetically closest relatives by phenotypic, physiological and chemotaxonomic properties. On the basis of the data from the present polyphasic study, we propose a novel genus and species within the family Flammeovirgaceae, with the name Fulvitalea axinellae gen. nov., sp. nov. Strain VI.18(T) ( = ATCC BAA-2395(T)  = LMG 26722(T)) is the type strain of Fulvitalea axinellae.
